The present invention relates to drinking troughs for animals and more particularly to means for providing heatedwater in the trough. v

An object ofthis invention is to provide 'a drinking trough in combination with a heating member whereby the water within the.

voir or the like, the device being so con-V structed as to receivea conventional submergedV heating stove or member.

A further obj ect of this invention is to pro-V vide in a device of this kind means for pre- .Z venting splitting or breaking of the exposed trough or troughs in the event the water accidently becomes frozen. y

A still furtherobject of this invention is to provide in a drinking trough means by which the sediment or the like maybe readily removed from the drinkingtrough, the trough embodying means for preventing the 'animals `from stirring up the sediment inthe bottom of the trough.

Vadvantages of this invention will in part be described in and in part be understood from the following detailed description of the present preferred embodiment, the same being il- '40 lustrated vin the accompanying drawings wherein Figure 1 is -a detail top plan view of a de-` vice constructed according to thegpreferredk embodiment of this invention Figure 2 is a sectional view partly in -detaily taken on the line 2 2 of Figure 1;

. Figure 3 is a sectionalview taken on the line 3 3 of Figure 1; Y c

c Figure 4 is a fragmentary side elevation of the water heating member, vand The above and various otherobjects and Figure 5 is a fragmentary sectional view taken on the line 5-5 of Figure 4,

Referring to the drawings wherein like numerals of reference designate corresponding parts throughout the several views, the numeral 10 designates generallya tank or reservoirof any desired capacity which is connected to a suitable source of supply bymeans of a pipe line 13 which is adapted to maintain i `the water in the reservoir 10 at a predeter- 60 mined level.

On the outer wall of the reservoir 10 there is positioned a drinking trough generally designated as 11 and if desired, each wall of the reservoir 10 may be Vprovided with a similar trough. The inner wall of the trough 11 is secured to the reservoir' 10 in anyvr de.v sired manner as by bolts vor the like and the ends together with -the outer. wall ofthe trough 11 are preferably positioned in up- 76 i wardly diverging relation so that inthe event the water within the-trough 11 becomes froz en, the walls of the trough will not become damaged through expansion of the frozen liquid. The bottom 12 of the trough 11 is 75 inclined downwardly and one end 14 is sub,- stantially deeper than the opposite end 15. At the lowermost point or closely adjacent the end wall 14, there is provided a drain opening or'outlet 16 so as to permit the sediment yaccumulating within the bottom 12'to` bedrained out of the trough 11.

A rack or grate generally designated as 17 is supported within the trough 11 by means f of uprights 18 which removably engage theV85 bottom 12 of the trough, this. grate 17 being mounted in substantially horizontal relation Within the trough 11, and in spaced relation to the bottom 12 so that when the animals c are drinking from the trough 11, they will not disturb the sediment which settles into the bottom of the trough. The outlet 16 may be provided with a suitable valve or plug 19 so 'that when desired, the valve or plug 19 i may be opened and the trough suitably cleaned.

A water circulating member or jacket gen-k erally designated as 20 is mounted within the reservoir or tank 10, this jacket 20 comi prisingan inner casing 21, an outer casing 1 member `26 may be constructed in any de` sired form and is preferably .of conventional j construction, that is, a heater which isy adapted to be practically submerged within the water positioned in the reservoir 1 0. The in- .15 ner casing' 21 preferably` projectsupwardly and above the top ringv 24 as disclosed at v27 so'ithat the entire` heating jacket 20 fma'y be submerged within the water in the reservoirv y1,0. The outer casing or shell 22 is provided adjacent the bottom thereof with an inlet opening 28 which communicates with the interior of the tank 10 so thatcold water within the tank may pass inwardly kthrough-this opening 28 and `into they jacket 20.

Adjacent theupper end of the jacket 20 there is provided a hot or warm water outlet 29 which is connected by' a suitable p1pe connection 30 to an inlet opening 31 in the trough t 11.k In this manner, the heated water within #9 the-jack`et20 will pass around the heater V26 and vvupwardly therethrough and into the trough 11. An outlet opening 32 is provided in thetrough 11 anda return conduit 33 is vconnected at one end to this outlet 32 and at Y the 'opposite end tothe jacket 20 at a point below the horizontal plane of the outlet 29.

In this manner, when the heated kwater passes through the conduit 30 and into the trough 11, itV will flow toward the outlet 32 and back into the jacket 2O through the ref turn pipeline 33. This return pipe line 33 may be connected to the outer kshell 2.2 at

. any desired point below thel level ofthe'outlet 29.y

' 4Q 'i :It will be obvious from thek foregoing that any water disposedwithin the heating acket 2()y will circulate thereabout and becoming heated willrise toward the ,top thereof and iiow outwardly through the outlet 29 and into 59 the trough llby means of the conduit-30.V

In the event the water within the jacket 20 'becomes unduly heated, the water is'adapted' to b e luy-passed, into thereservoir or tank 20 by means of by-pass outlets or ports 34 and 35. These ports 34y and 35 are positioned in theouter casing 22 adjacent the top thereof andare preferably spaced vertically, the outlet 34 being preferably coplanar with the` outlet-29 and the outlet-35 being preferably 9 disposed upwardly therefrom and adjacent the top ofthe outer casing 22.

v A guide'member 36 is secured toy the outer casing 22 and is provided with complementary openings which register with the 95 Openings34 and 35inthe outer casing 22 and 'f inlength than the inner casing 21 so that the kbe provided with a yreverted upper end 38 when the water within the'ja'cket20 becomes aslidable closure 37 engages the ide 36 and when in lowermos't position is a apted to close both of the openin s 34 and 35. When the water becomes undu y heated within the 'acket 20, the slide or closure member 37 may e pulled upwardly, thereby permitting the water within the jacket 20 to be by-passed into the'tankor reservoirlO.'r

This outer casing 22 is preferably shorter 7`5 inner casing'21m'ay, if desired, rest on the bottom of the tank 22 and the outer casing 22 will be disposed upwardly from the bottom of the tank 10. ,The closure member 37 may 80 constituting ai handle or means by which the closure plate may be readily moved upwardlyvinto aposition permitting thewater within the jacket 20 to flow outwardly through the openings 34 and 35.- By disposing the top of 6 5 thejfacket 20k below thelnormal vsurface of the water within the tank 10 in the yevent the 'surface of ythe water Vwithin the tank'. 1K0

should become frozen, the water within'the jacket 20 will not become frozen Lso as to'y pre- 9 event the free circulation of the water to the ytroughs 11. v

In the use of this device, the heate126inayv be disposed within theinner casing 22 and sufficiently heated, the heated. Waterwill'y rise toward the top yof ythe jacket 20 and flow outwardly thereofl through the outlet-29and the conduit 30'i'nto the trough 11. The lflowV of water :will then kpass along the ytrough 11 towardthe outlet 32 and' back into the jacket f 2()` at a point below the level of the outlet 29 throughthe conduit 33. The 'jacket 2()r will be maintained'in filledi condition at all times through the inlet vopening 28 which communi-v cates 'with the interior of the'tank l0. i

y It is, of course, understoodthat various changesandmodifications may vbe made in the details of construction and design ofthe abovespecifically described embodiment of @e0 this invention without departing' from the spirit:v thereof, ysuch changes andjmodificationsbeing restricted only by the scope of the followingclaims. i Y
